DUMPiNG-CAR.

SPECIFICATION forming part of Letters Patent No. 71 5,312, dated December 9, 1902.

Application filed October 9, 1901. Renewed May 7, 1902. Serial No. 106,342. (No modell) To aZZ whom t may concern.-

Beit known that I, JACOB J. SO UDER, a citizen of the United States, and a resident of Washington, in the District of Columbia, have invented a certain new and useful Improvementin Dumping-Cars, Of which the following is a specification.

The dumping-car to which my invention relates is one in which the discharge is down- Ward through the bottom of the car, the discharge openings therein being closed by hinged drop-doors.

My invention consists of certain improvements in this kind of dumping-car, which Will rst be described in connection with the accompanying drawings, forming part of this specification, and will then be more fully pointed out in the claims. In the drawings, Figure lis a side elevation, partly in vertical section, of a car embodying my improvements, Fig. 2 represents the body of the car,one half in plan and the other half in horizontal section, with a portion of the A center sill removed to expose the parts below. Fig. 3 is an end elevation of the car. Fig. 4 is a section on line 4 Li, Fig. 2, omitting the structural details of the end of the car. Fig. 5 is a detached view, in sectional elevation, of a portion of the winding-shaft and the locking-shaft, together With the drawbar box and bolster-plate. Fig. 6 is a crosssection of a structural detail hereinafter referred to. i

The particular car shown in the drawings is a freight-car designed more particularly for the transportation of coke and preferably made of structural steel.

The body A ofthe car is made of a framing, suitably braced, to which are secured horizontal angle rails or bars, which form the sides and ends of the car. In the sides of the car are a suitable number of sliding doors X, each of which is preferably divided horizontally and longitudinally into two sections, which can slide back and forth independently of each other. These parts are of known construction,l and inasmuch as they form no part of my invention they require no further description.

The car is one having fixed inclined bottom sections extending from the longitudinal center line of the car outward over the Wheels thereof and inwardly-inclined bottom sections hinged at their outer edges to the side sills of the car, opening outward from the iixed sections and discharging the contents Outside the Wheels of the car, in combination with means outside of or below the fixed sections for lowering and raising the hinged sections synchronously, in which respect it resembles the car which is the subject of my Patent No. 676,103, of.June 11, 1901; and the fixed inclined bottom sections form, in effect, a central longitudinal metallic support or girder of A shape in cross-section, which eX- tends the length of the discharging portion of the car and is rigidly attached to the end walls of such discharging portion, in which respect it resembles the car which is the subject of my Patent No. 652,930, of July, 3, 1900.

Under my present invention the central longitudinal A-shaped girder extends from end to end of the car-body, and it receives, supports, and forms a housing for the drawbars and their appurtenances,the chain-winding shaft for the hinged bottomsections, and the body-bolster plates for the king-bolts which connect the Wheel-trucks to the body of the car. It is, in fact, the center sill of the car. I also locate within the same A-shaped center sill a longitudinal shaft, which is operated from Outside the car, preferably from the end of the oar, and is designed to actuate and control one or more locking devices 10- cated Within and secured to the A-shaped sill and adapted to engage the chain-Winding shaft at one or more points throughout its length. The central A-shaped sill is shown at A. It is made, preferably, of sheets of steel properly riveted together and braced. It extends from end to end of the car and at intervals throughout its length is rigidly connected to the body of the car by inclined stay-bars a, which preferably are angle-bars and are formed as continuations ofthe vertical side frame-bars a of the body of the car. At the ends of the car it is rigidly secured to the end Walls b of the discharging portion of the car. v

The side sills of the car consist of channelbars c. The end sills are shown at d. erepresents cross-bars, which extend across between and are connected to the side Walls of the car at intervals throughout its length to brace and strengthen it. At the points where the inclined walls of the /\sill A pass the truckwheels `W they are slightly raised and given v fixed an operating handle or lever/n..

a hood-like form, as indicated at A, in order to allow all needed play to the wheels. The inwardlyinclined bottom sections, which close the discharge-openings in the car, are shown at B. There are preferably four of these doors, two on either side, and they are hinged on their upper and outer edges to the side sills ot' the car, as indicated at f. The doors B are lifted so as to close the dischargeopenings by means of chains g, in suitable number, attached at one end to the doors and at the other end to a winding-shaft C, which is housed and supported in suitable bearings in the /\sill A' and extends the length ofthe car. It protrudes through one end of the car, and this protruding end is squared to receive an operating-handle and is provided with a pawl-and-ratchet device h to retain it in wound position, as indicated in Fig. 3.

In order to remove from the winding-shaft the strain which otherwise would come upon it when the doors are closed and the car is loaded, I combine with it one or more locking devices at a point or points within the A-sill A. I have shown it provided with one such device, but more can be employed, as desired. In the present instance one member of the locking device consists of a star-wheel l,which is fast upon winding-shaft C, and the other member consists of a notched or toothed dog 7c, housed in and pivoted to a suitable portion of the A-still A', in a position to overhang the star-wheel 7l and to be lowered and lifted into and out of engagement with the same. For this purpose its free end is jointed to a link Z, which at its other and lower end is in turn jointed to a radial arm m, fixed on and moving with a locking-shaft D, extending lengthwise of the car and housed by and supported in suitable bearings in the /r\sill A', in which bearings it can rock, so as to lift and lower the locking dog or dogs la. This lockingshaft protrudes through to the outside of one end of the car, and on this protruding end is So long as this operating-lever is in locking position, theA locking dog or dogs will be forced and positively held down in engagement with the star wheel or wheels i' on the winding-shaft. Meanssuch as, for example, in my allowed application, Serial No. 51,919, filed March 19, 190l-should be provided for securing the locking-lever n in this position, so that it may not be tampered with or accidentally misplaced. To open the doors B and discharge the contents of the car, the pawl and ratchet members of the device h of the winding-shaft C should first be disengaged from one another, after which the lever n is moved to rock the shaft D in a direction to lift the locking-dogs k from their star-wheels i'. This unlocks simultaneously all the doors B, which at once drop and swing open.

At each end of the car there issecured and housed in the A-sill A the guide and supporting-frame in which the draw-bar and its appurtenances are mounted. This frame, which may be of any approved structure, is shown in the present instance as consisting of the longitudinal angle-bars o, parallel with one another and at the proper interval apart to afford a frame of the proper width. Between them is secured the channel-bar p, which forms the bottom of the frame. Superposed on the angle-bars 0 are Z-bars fr, which constitute the upper part of the side walls of the frame. Between the contiguous faces of the flanges of the Z-bars and the angle-bars o extend the inner ends or edges of supporting-plates s, which are secured at their outer ends to the inner walls of the A-sill A. The contiguous flanges of the bars o and r are riveted together and to the interposed edges of the plates s. This makes a trunk or box like frame in which the draw-bar and its appurtenances can be fitted and held.

The bolster-plates of the car also are contained in and housed by the A-sill A. In this connection I can conveniently use the draw-bar frames for supporting the plates. To this end the rear portions of the anglebars o of each draw-bar frame are extended beyond the rear ends of the Z-bars r, as indicated in Fig. 5, and on these extended end portions rests the bolster-plate t, which also extends forward between the contiguous iianges of the bars 0 and r. This plate is riveted securely to the side walls of the A-sill as well as to the bars o and r. In order to brace and support the bolster-plate against upward thrust, I interpose between it and the upper partof the A-sill A' two triangular skeleton angle-bar frames u, located back of the Z-bars r. The inclined sides of these frames closely fit the inclined inner walls of the sill up to their apex or meeting-point. Their bases rest upon the plate t, and they are firmly secured to the plate and sill-by riveting or other suitable means. The features last above referred to are illustrated more plainly in the sectional View, Fig. 6, in which u is one of the triangular skeleton frames andt is the bolsterplate attached to angle-bars t', which in turn are secured tothe walls of the A-sill. The two frames u are parallel with and at an interval from one another, and in that portion of the plate t which is included between them is formed the hole for the king-bolt, as indicated at w. The triangular opening in each frame u may, for purposes of added strength and stiffness, be closed by a metal diaphragm pierced with openings for the passage of the winding and lock shafts.

Brace-frames similar to frames it may be tted and secured to the sill A at intervals throughout its length, as shown, for example, in Fig. 4, to secure stability and solidity of structure.

I remark that in lieu of chains for shutting IOO IIO

the doors I may use suitable systems of 1evers connected to and operated by the Winding-shaft.

The central A-sill, connected as it is to the sides and ends of the framework of the body of the car, becomes, with the bolster-plates which it carries, the car-bolster. By this construction I dispense entirely with the bodybolsters and longitudinal center or draw sills usually employed. I thus materially reduce the weight of the car and am also enabled to bring the discharge-sections close down over the car-trucks and to more advantageously positionand distribute the Weight of the contents of the car.

Having described my improvement and the best Way now known to me of carrying the same into effect, what I claim herein as new, and desire to secure by Letters Patent, is as follows:

1. In a dumpingcar all-shaped center sill extending the length of the car-body, and whose inclined walls constitute fixed inclined bottom sections extending from the longitudinal center of the car outward over the Wheels, and doors hinged at their outer edges and restin g against the outer edges of the xed sections when closed, in combination with a longitndinal Windingshaft housed and mounted in said A-sill, connecting means between the doors and said Winding-shaft, a locking device mounted Within the A-sill one member thereofI being secured to the sill and the other tothe shaft, alongitudinal locking-shaft, connected to and adapted to positively operate the locking device, and housed in and supported by the A-sill, and protruding through and beyond the end of the car, and an operating-handle on said protruding end, substantially as and for the purposes hereinbefore set forth.

2. In a dumping-car, a`\shaped center sill extending the length of the car-body, doors hinged at their outer edges to the side sills of the car and resting against the outer edges of the inclined Walls of the A center sill when closed, a longitudinal Winding-shaft housed and mounted in the sill connecting means between said doors and winding-shaft,and drawbar-supporting frames andbody-bolster plates also housed in and secured to said sills, all substantially as and for the purposes hereinbefore set forth.

3. In a dumping-car, a llshaped center sill extending the length of the car-body, and bolster-plates housed in and secured to said sill, as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this lst day of October, 1901.
